- STEVAL-POE003V1, Reference Design represents a PoE Class 8 converter designed for high efficiency conversion over a wide load range. It is based on the PM8805 PoE-PD interface compliant with the IEEE802.3bt standard, and a DC-DC forward active clamp converter driven by the PM8804 PWM controller. The PM8805 system on package device embeds two active bridges and an IEEE802.3bt compliant Powered Device (PD) interface. It can be used in all medium-to-high power 2P and 4P high efficiency PoE and PoE+ applications such as point of sales and retail logistics devices
